"The Adventures of Huckleberry Finn" by Mark Twain, read by Dick Cavett, abridged by Sue Dawson. Listen for Pleasure. Casting is crucial in audiocassettes. The light, cheerful, urban voice of television interviewer Cavett is so familiar that when he lapses into an ersatz, all-purpose Southern drawl for Huck and company, the effect is lamentably obtrusive and unconvincing. The abridgement is efficient, but there must be more appropriate material for Cavett to read.
